last resort

Okay, I have done a virus scan with AVG-Free, Spybot S-D, Adaware, have run rootkit revealer and everything has turned up clean. Ran the spyware detector from pcpitstop.com and it said I had an instance of bifrost, but wouldn't show me where, and wanted me to pay $30 to clean it. Anyway, the problem I'm having is that occasionally my CPU usage will spike, freezing hte computer, for a few seconds at a time. This will go on for a few minutes before settling down and things go back to normal. Here's my hijack this log, I'm not sure what else to do if you guys can't find anything either!.
